Your code so far

Link to the challenge:

What browser are you using and on what type of device?

Most code editors identify themselves in the header such as:

Your Title Here This is for "Alleycode HTML Editor" others are similar

Google Chrome Browser I am using it on Laptop.

You need “Hello World” inside h1 tag instead of just “Hello”.
See if that helps.
